tions after each operation thereof, and are carried upon a suitable shocker truck adapted to be attached to and trailed at thc rear of a harvester. Y

I will first describe the shocker truck and the power and draft connections therefor in order that the relation of the shocker' to the harvester may be clearly understood.

The shocker truc/c.

This truck is of the sulky type 'and is shown herein to be adapted to trail'at the 'rear and on the stubblew'ard side of a It may, however, obviously be used withA a harvester of another type if desired. i

It' comprises a substantially horizontally disposed frame formed of rigid side membersv 1 and 2 (Fig. 1) connected lat their front ends by a transversely extending member 3, and at their rear ends by a bowed por- -tionfl' of the truck axle 5. In the construction shown, the power for the shocker is 'generated by its own wheels (3, rather than fromthe harvester, and is conveyed therefrom .through sprockets 7, which may be suitably fastened to the wheels 6, to a countei-shaft 8 extending transversely across the shocker frame at a point intermediate its` ends, and provided with suitable slip-clutch connected sprockets 9 upon its free ends adapted to be rotated by suitable chains 1() connecting the same'with the sprockets 7.

The draft connections for the truck (Fig. l) aremadc at t-he end of a diagonally extending coupling bar-11 'which is fixed at its rear end to the rear end of the frame and ex! tends diagonally across and beyond the front of the same toward 'the harvester, where it is pivotally and adjustably connectedto a draft bar 12. This draft bar 12 is supported by acoupling frame connected at its inner end to the harvester by means of suitable clips 13 (Fig. 10), and comprising two channel bars 14 having converging ei'ids 15 adjustably connected to each other by means 0f a plate 16 and bolts 1T. As shown, the dra-ft bar 12 extends over the ends of the bars 14 and is provided at its/inner end with a Harige 18, which maybe suitably fastened to the harvester frame. At a point .intermediate its ends the draft bar 12 is adjustably connected to the converginuy ends 15 of the bars 14 by means of a suitablev clip 19. The outer end of the draft bar is provided with al vertical slotted plate 20 to which is adjustably attached the vertical shank 2l of a caster wheel 22.

Fixed to the coupling bar 11 at a point ,intermediate its ends is a longitudinally eK- tending tongue 23 braced transversely by a bar 24 attached to the bar 11 and also braced sheaves in 'proper position to be operated` upon by the shocking mechanism after their ejection from the binder, the tines 28 preventing `the sheaves from passing beyond the fork and causing them to fall on the fork trip,- hereinafter described.

Carried upon the rear of the shocker frame 1s the sheaf-rece1vmg receptacle or cradle towhich the sheaves are delivered` from the binder and in 'which the same are compressed and bound. 1n a shock.

The shouf-"leceim'ng cradle.

This sheaf-receiving cradle normally reclines upon the shocker frame in the position shown in Figs. 2 and 3, and is adapted to be tilted rearwardly about its pivot upon the rear end of the latter to discharge the shock therein. I

In the form shown herein tbc front or inner end of this cradle is held slightly higher than the opposite end of the samel and is supported near the middle ofthe frame on a transversely extending brace bar 29, carrying standards 30 connected by a base bar L The sheaf-receiving cradle itself comprises a longitudinally extending center member 32 and a plurality of spaced side members supported by and attached to an underlying U-shuped member 33, as

well as upstanding outwardly bowed guard wings 34 and a transversely extending connecting member and bar 3G, which serve.

to connect the forward and rear ends respectively of the members and 33, and form therewith a substantially trough-shaped cradle provided with an inclined bottom and substantially vertical 'side walls (Fig. 2). Upon the front end of the cradle vertically extending sheaf positioning arms 3(1 are provided which coil icratc with similar arms i 342 carried by the shocker frame. Upon theA bottom of the cradle a plurality of subst-ans, y

tially vertically exteluling sbcaf }')iercing.;

tinesBl3 are mounted. As heretofore indicated, this Vcradle adapted to swing vertically upward and backward to slieaf dis charging position, being pivoted at its rear. 'I

end upon the bowed portion of axle Cooperating with this cradle inI a manner hereafter more specifically described is an end-gate shown in the form of a seriesof tines pivotally mounted at the rear of the frame on a txansverscly extending bar andi,

normally occupyig the position shown in l*1 igs. 2 and 3. vAs illustrated these tines are carried on a transversely extending rod or shaft rotatable with respect to the bar 36 in bearings 37, the rod'being shown at 38, and provided with a plurality of transversely spaced tines 39 normally extending vertl-4 cally upward to form an end-gate for the cradle. 4

( operating with the sheaf-receiving "cradle and adapted to deliver the sheaves ejected from the binderdeck to the sheafreceiving cradle and turn them butt end rearward during the process of delivering them so that their butts protrude through the tines 39 of the cradle end-gate, is the sheaf delivering member. v

staaf delivering member.

This sheaf. delivering member is shown to be in the form of a pivoted fork adapted to l oscillate back and forth. about its pivot through an arc of-*gsubstantially'QOOo in mov'- ing from sheaf receiving position adjacent the harvester deck (Fig. 3) to 'shea-f discharging position abovey the cradle (Fig. 8l.

This fork is pivotally mounted on vertically extending standards 40 carried on the forward end of th'e shocker frame and is rotatable in end bearings 41 thereon with a transversely extending fork shaft` 42, as'

shown in Figs. 1, 16 and 17, the fork itselfl being indicated as 43.- In sheaf receiving 'position the'sheaf carrying end of this fork rests u on the `transversely extending bar 24, carrie by the shocker frame, at a point between the'gu'ard'rail 26 and thetongue 23 and adjacent the binder deck of the harg vester. Since this bar serves to establish one of the limits of travel 'of the fork during the operation of -illing the cradle, in order to absorbthe'detrimental shocks and the rebound of the fork incidental to its contact therewith, cushioningfmaterial 44 (Fig. 8) may be provided on vthe lfork. Obviously,

the fork may, however, be cushioned by other means than that shown, andit is not necesfork occupiesthe position shown "in Fig. 8, wherein it is above themsheaf and at the bottom of the -cradle afs;` tlf sheaf is deposited therein. Obviously-,i asthe cradle is filled and the sheaves are piled up therein, the

fork will be gradually limited in its movement, as hereinafter more'fully described. Vlt is to be noted that the tines 45 of this fork are carried upon the free end of the same inV a plurality of spaced pairs and project upward in sheaf-receiving position and downward in sheaf-delivering position so that the sheaves falling from the harvester deck are readily and securely impaled thereun in one position and are readily disenaged therefrom inthe other osition. It is urther to be noted. that the structed that it; pivot point is at one side of its center line, thus enabling the same to co` operate with the slanting cradle bottom to position the sheaves and to be readily sepa# ork is so com' rated from the latter after they have been deposited in thc cradle.

Coperating with this fork and operatin'gy Sheaf delivering mechanism.

This mechansm is operatively connected between the folk or rocker shaft 42'and the shocker wheels 6, and transmits the power .from the latter in such a. manner as to oscillate. the fork alternately in opposite directions fr om shea f receiving to sheaf dischargin position.

t comprises :t transversely extending stubshaft 46 (Fig. J journaled insuitable bearings carriedby standards 47on the forward end ofthe basi frame. -Theouter end of this shaft is prc vided with a sprocket-48 and This clutch, 11s shown in Figs. 1, 13 and 'l -15, comprises a clutch member 51, carried upon the .shaft 46, having a row ofv studs 52 on one surface thereof, and coperatin with a crank arm or coperating clutc member 53 loos ely mounted onthe shaft 46 adjacent member 51. This member 53 is provided with t lug 531 at its shorter end,

having a slot tierein to receive a pawl 54. This pawl is pivotall-y connected to said lug and isV eccentric illy mounted with respect to the axis of said crank arm on a pin 532. A

laterally projecng arm 55 is adapted to be engaged by any 4one of the studs-52 to cause he same to thel yas the shaft and :lutch member 51 to rotate i together. The pawl 54 is provided with a clutch controlling arm 5F that protrudes radially beyond the peripl ery of the'clutch (Figs. 1,`

normally holds the clutch members disengaged from each other.- The member 58 is pivoted to the 'f :ame at a point intermediate its ends, its i lrward end in engagement with the rear end 59 of a longitudinally extending trigger rod 60 (Figs. 1, 3 and 6) hav ing bearings 6()1 and 602 on the frame and the guard rail 26 adjacent the end of fork Aand through it 43 and in the path of a sheaf delivered from the harvester.

The power connections between the clutch and the rocker shaft 42 (Figs. 7, 13, 14, 16 and 17) include an arm 62 pivotally connect ed to the outer end of the member 53 and carrying a substantially rectangular housing 63 through which a. link 64 is slidable.

.This link is pivotally connected at its upper'e'nd to a stud or bolt 65 which projects laterally from the lower end of a crank arm 66 freely rotatable on the end of the rocker shaft 42. In a preferred form the free end of the link 64, within the housing 63, carries un abutment plate, 6T forming a seat for one end of a spring 63 coiled about the link. The other end of this spring bears against the opposite end of the housing The spring 68 itself is preferably inclosed in a suitable casing G9 carried by the housing 63. The crank 66, to which the lilik 624" is connected, is provided with a hub 70 (Figs. 16 and 17) freely rotatable on the en d'- of the shaft 42 and having a circumferential slot 71 formed in itl through which protrudes a stud or projection 72 fixed to the rocker shaft 42. The rocker shaft 42 is also provided With a laterally extending lug 73 hav ing an arm 74 connected to a spring 75 carried on .a supplemental supporting frame 76 (Fig. 6).`

The operation of this sheaf delivering mechanism is as follows: W'hen a sheaf is dropped upon the tripping finger 61 the trigger arm is swung about in itsV bearings. This causes the rod 58 to be disengaged from the clutch arm 56. The clutch spring 57 then swings the pawl 54 into engagement with one of the studs 52and the ,two members of the clutch are locked together in a Wellio'wn manner. The rotation of the shaft vd thus imparted to --the shaft 46 and the movement of the latter is impar-tedl to crank arm 66 through the resilient connection 62, 64, 68. As soon as the member 66 has moved through a suilicient anglelto cause the ind wall of the slot 71 in its hub to jengage with the stud 72 on the rocker shaft 42, the rotation of the shafts 8 and 461is transmitted tothe rocker shaft 42 to the sheaf delivery fork 43, causing the latter to swing upward -and backward about its pivot from sheaf receiving position to sheaf delivering position.

i It is to be noted that the clutch is connected during a complete revolution of the shaft 46 and that while the clutch is still connected the pivotal connection between the latter and. the crank 66 is thrown through a complete revo1ution,turning the latter about its pivot automatically in one direction f movement to drive the sheaf delivering fork to shcaf delivering position, and then automatically reversing the direction of movement to throw the fork back to sheaf receiving position ready fo'r the next operation. It is further to be noted that in the movement of the. fork from sheaf receiving to she-af deliveri sition, and from sheaf deliver-iwr t receiving position, a certain amount o.. J4)lay is permitted between the fork and its driving mechanism due to the provision-of the slot 71 .in the hub 70, andthat the fork 43 independently movable by gravity relative to its 'driving mechanism after `it passes the vertical position and its weight is displar'd to one side of its pivot. providing t play it is made possible to build up ashock under impact of the fork mid other advantages are obtained, inclufngthe removal of deleterious shocks and jars in operating the mcchanisn'i and increased facility of sepa rating the fork from the sheaf when the latter is bein delivered to the cradle. It is to be noted tiat the spring 7 5 is automatically placedunder tension as the fork moves to or returns from s'neaf receiving position, so that this spring acts to restrain the, movement of the fork in either direction, thus acting to assist in the cushioning of the fork and prevent the rebound of the same. This spring also performs another function; namely, that of accelerating the return of the fork from itsv limits travel and at the same time also assists the spring 68 in the withdrawal of the fork tines from the. sheaves as they are deposited in the cradle. Obviously, the clutch members 51 and 53 re lease each other automatically when the clutch arm. 56 is again engaged by the trip 58 at'the end of cach complete revolution of the shaft 46 and to and fro movement ofthe sheet'. delivery arm, so that 'the partsrare' with quick hammer-likeblows and then being innnmliately and quickly returned to sheaf receiving position. v

' Cooperating with the automaticmeenanisin for-.actuating the sheaf delivering fork inits movement to land fromfthe cradle, and with the sheaf receiving cradle Litself, isthe iis automatic shock binding and compressing mechanism which acts upon the sheaves Shot-7c binding and compressing mechanism.

Both of these mechanisms are operated from the power shaft 8 and are arranged upon the sides of the sheai receiving cradle at the back oli-the machine frame.

I will first describe the binding mechanism: As shown in Fig. l., a gear77 is loosely carried on the counter-shaft 8 and meshes with a gear 78 fixed on a longitudinally extending stub shaft 7 9 carried byV the frame. This shaft is provided With a sprocket 80 near its rear end, which has a transversely extending chain connection 8l with a sprocket 82 carried by a longitudif nally extending binder or knotter shaft 83. As shown, this knot-ter shaft extends substantially parallel 'with the cradle at one side of thee-ame, and is journaled in a pc,- sition substantially above the frame member 1. The shaft 83 operates a knotter 84, and also acts as a power shaft for the compressing mechanism and the sheet dischargmechanism hereinafter described, The knotter 84 may be of any desired, type; such, for instance, as the Appleby type, comprising a breastplate having a needle receiving slot 841 therein, and any preferred form of knot tying mechanism connected to a knotter operating wheel 8.42. Coperating with the knot tyingr mechanism and operated by the knetter shaft 83 through transversely extending link connections 85, 86, 87 and a shaft 88, is a binding needle 89, operable upon rotation of the shaft 83 to move trans versely across the sheaves in the cradle and copernte with the knotter S upon the opposite side of the frame, Carried by this bindlng needle 89 is a chord-like, resilient,

flexible, shock-compressing connection 89',

preferably formed of sections of coiled spring and chain, which acts to remove needleand fatimethat -it causes a substantially uniform pressure to be exerted upon shocks of varying size.

The operation of this binding mechanism is as follows: In the normal position of the needle 89 the twine fed out therefrom extends between the same and the knotter 84, as shown in Fig. 2, and across the cradle, so that the sheaves delivered to the latter carry the same .to the bottom of the cradle. When the cradle is filled the binding mechanism is operated. 83, through the connection of4 the gear 78 to the countershaft 8, the links 85, 86, 87 and shaft 88 are actuated to throw the needle 89 about its pivot transversely across the frame presser arm 9] Upon therotation of the shaftv 'the inner face at a point substa ntially midway between the ends of the sheaves. When the knot tying end of the needle passes through the knotter hreastplnte the twine is automatically tied about the sheaves in the cradle in a wellknown manner to form the same into a shock. Upon the continued rotation of the knetter shaft Sil the parts are then automatically returned to their initial positions, the twine being `:ut in a well-known manner and the needle 89 bein thrown backward about its pivot and feeding out the twine so that when the next sheaf is deliyered by the sheaf ldelivering` mechanism to the cradle, this shear will curry the twine to the bottom of the cradle and the sheaves subsequently delivered thereto will be deposited upon the top of the twinr ready for the next binding operation.

The shcaf compressing mechanism coperates with the sheaf bindin mechanism, acting to relnov e the sheaves rom the path of the binding needle during the binding operation, and at the same time compress the sheaves so that s more compact shock is produced and one which requires a smaller amount of twine to be used in the binding process.

' This mechanism is likewise operated from the knotter or binder shaft 83 and is arranged to operate simultaneously with the binding needle` 89. It comprises a cam 90 carried intermediate the ends of the 'Shaft 83 and operable, u hen rotated by the shaft 83, to rock a compressor arm 91g iournaled in the frame adiscent the knetter, about its pivot, as shown in Fig. 4, in such a manner as to compress ;hc shockat a point in front of the` knotter and force the grain out of the path of the nee lle'. As illustrated, the comand the binding needle 89 move in substnntially parallel planes and are movable simultaneously in opposite d. rcctions, so the; their action is substantially simultaneous during the'binding operation. When thel shaft 83has turned through the desired movement; z'. c., when the binding operation is completed, the arm 91 is swung backward to tte dotted line position shown in Fig. 4; by ary suitable means; as, for instance, a spring; 92 (Fi 5.) j

The twine ior the Einding operation is supplied from a suitable twine receptacle or box 93, carried, preferably, upon the frame at the side of the cradle adjacent the pivot of the binding needle, and in such a position that the twine may be readily passed through the glides on the binding needle in the usual manner. Copelfating with the knot tying me :hansm in the control of thel '125 twinez and operating -to reduce the amount of twlne required 1n the shock bmding operation, is a ticker arm 9@ movable across of the knetter breastplate.
